$a\left(a+b+1\right)+b\left(a+b+1\right)-\left(a+b+1\right)$
Learn how to solve special products problems step by step online. Solve the product (a+b+-1)(a+b+1). Multiply the single term a+b+1 by each term of the polynomial \left(a+b-1\right). Multiply the single term a by each term of the polynomial \left(a+b+1\right). When multiplying two powers that have the same base (a), you can add the exponents. Multiply the single term b by each term of the polynomial \left(a+b+1\right).
